Yet another “fun” in the encryption filter path…
If I encrypt/decrypt all non cached paging IO, on NTFS, compressed
files will be double encrypted… (or single encrypted, not sure due to
the use of byte flip at this time)
How do I handle this situation?
After observing the flags (Irp->Flags, FileObject->Flags and
IrpSp->MinorFunction, IrpSp->Parameters.Create.Options) I cannot find
any difference from ordinary reads or writes…
